Is it safe to lock bootloader?

[klaasklever]

thanks for the correction @yvmuell , though i don’t understand it fully the way you describe. it’s not in the rollback tutorial either, where does one find the correct commands in the right order?
i am not sure if i ever will lock my bootloader again (device theft is not my biggest fear) when i get my fairphone back debricked. but a detailed explaination or more details in the tutorial would definitely help, i believe.

Yes the Fairphone tutorial is not good or complete.

Those information is spread over the forum in various topics

Can't flash stock FP4 ROM

Definitely check fastboot flashing get_unlock_ability immediately before locking. And don’t boot into Android after flashing it, the first boot resets it to 0 (The reason being that’s how you get your phone delivered and there are apps that check for that). Flash → Check → Lock

I personally would also not lock my bootloader.

Update: got an OTA update, installed it without problems. Made sure this was the right security patch level and was able to lock the bootloader again.
